1. You asked for material suitable for Class 9 level. 2. Class 9 math typically covers algebra, geometry, statistics, and number systems. 3. For example, an algebra problem might be solving linear equations such as $$2x+3=11$$. 4. To solve this, subtract 3 from both sides: $$2x=8$$. 5. Then divide both sides by 2: $$x=4$$. 6. This is a basic example tailored for Class 9.
